PUMP-ROD CONNECTION.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed June 3, 1907. Serial No. 377,077.

To all whom it may concern:

Be it known that I WILLIAM E. BOYD, citizen of the United States,residing at Springview, in the county of Keyapaha and State of Nebraska,have invented new and useful Improvements in Pump-Rod Connections, ofwhich the following is a specification.

My invention pertains to pumps; and it contemplates the provision of'simple and easily 0 erated means through the medium of whic the pistonrod of a pump may be connected to a hand lever and the pitman rod of awindmill, alternately.

\Vith the fore oing in mind the invention will be fully understood fromthe following description and claim when the same are read in connectionwith the accompanying drawings, forming part of this specification, inwhich:

Figure 1 is a view partly in elevation and partly in vertical sectionillustrating a pump, a portion of the pitman rod of a windmill and mynovel connecting device; the said device being shown as effectingconnection between the piston rod of the pump and the hand leverthereof. Fig. 2 is a transverse section taken in the plane indicated bythe line 2-2 of Fig. 1 and showing the parts of the connection on anenlarged scale. Fig. 3 is an enlarged view, partly in plan and partly insection, of my novel device, removed.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is a portion of a windmill tower.

B is a portion of the pitman rod of a windmill; said rod being providedin its lower end with a socket 0. having transverse apertures b inopposite walls thereof.

0 is a pump having a hand lever D and a piston rod E; the latter beingequip ed with an upper flattened portion 0 in w ich are transverseapertures d and e, and F is my novel connecting device. The said deviceF is made of steel or any other metal suitable to the purpose for whichit is intended, and it comprises a pin f, preferably of circular form incross-section, having adjacent to its opposite ends an aperture g and alug h and also having at its rear end a finger piece is, a keeper Zhaving an arm m straddling and pivotally connected at n to the lug 7Land also having a finger-piece p extending rearward from the arm m, anda coiled spring 1' interposed between the finger-pieces 1c and p andheld in position relative thereto by projections s on the inner sides ofsaid fingerpieces. In addition to the features mentioned the keeper Z isprovided at its forward end with an arm 1? which terminates in a reducedportion u adapted to enter the aperture gin the pin f after the mannerillustrated in Fig. 3. By virtue of the device F being constructed inthe manner described it will be observed that when the finger-piece p ismoved against the action of the spring r toward the finger-piece 7c, theend a of the keeper 1 will be removed from the aperture g in pin f, andsaid pin f may then be inserted in and removed from devices to beconnected with the same facility as an ordinary pin. It will be noticed,however, that when the pin f has been passed through two devices to beconnected, and the finger-piece p is relieved of pressure, the spring 1will operate to return the keeper Z to the position shown, relative tothe pin and said keeper will then serve to efiectua ly prevent casualdisconnection of the pin f and the device F as a whole from the devicesthat are to be connected.

In the practical use of my novel connecting device F for the specificpurpose stated it. will be seen that when it is desired to connect thepump rod E and the hand lever D, it is simply necessary to pass the pinf through registered apertures in the rod and lever, and then relievethe fingeriece p from pressure when the keeper Z wil immediately assumeand remain in the position illustrated in Figs. 2 and 3, relative to thepin f, and consequently will serve to effectually prevent casualdisplacement of the pin and disconnection of the hand lever D from therod E. When the hand lever D and the pump rod E are connected, asstated, it will e apparent that the pump may be operated in the usualmanner by hand.

When it is desired to operate the pum through the pitman rod B of thewindm'fi instead of by hand power, my novel device F is manipulated topermit of the withdrawal of the pin f from the pump rod E and hand leverD, and subsequent to said withdrawal, the upper end of the pum rod E ispositioned in the socket a of the ro B, and the pin f is placed in theregistered apertures of said rod and socket after which pressure isremoved from the finger-piece p so as to enable the keeper Z to assumethe position shown in Fig. 3, relative to the pin f, and in that waypreclude casual displacement of said pin and disconnection of the pumprod E from the pitman rod B. When the pitman rod of the windmill isutilized to actuate the piston rod of the pump, it will be apparent thatthe hand lever D will remain idle and hence will not be liable to strikeand injure persons standing by the pump.

It will be apparent from the foregoing that my novel connecting device Fis of such construction that the pump may be expeditiously and easilychanged from a hand operating pump to a power operated pump and viceversa, and this without the employment of skilled labor or tools, andwith the expenditure of but little effort on the part of the operator.

While designed more especially for use in connection with a pump and thepitman rod of a windmill, I desire it understood that my novelconnecting device is adapted to be used to advantage for other purposes,such for instance as connecting parts of different kinds of machines.

The construction herein shown and described constitutes the preferredembodiment of my invention, but I desire it understood that in practicesuch changes may be made as fairly fall within the scope of my inventionas claimed.

Having described my invention, what I claim and desire to secure byLetters-Patent, 1s:

A devicefor the purpose described, comprising a pin terminating at oneend in a finger-piece and having a diametrical aperture adjacent to itsopposite end and also having a lug adjacent to the inner end of saidfingerpiece, a keeper having an angular arm at one end pivoted to thelug of the pin and an angular arm at its opposite end arranged to enterthe diametrica aperture of the pin and also having a linger-pieceextending outward from its first mentioned arm and arranged opposite thefirst mentioned finger-piece, and a coiled'spring interposed between andconnected with the said fingrieces.

In testimony whereof I have ereunto set my hand in presence of twosubscribing witnesses.
